What private well owners commonly test for
- Total coliform and E. coli bacteria: the most common recommendation, at least once a year
- Nitrate: especially near fields, livestock or septic systems
- Total dissolved solids, hardness and chloride: affect taste, scale and appliances
- Other contaminants such as arsenic or fluoride, depending on your area and concerns
When to test
- At least once a year for bacteria
- After any repair, new pump, or flooding near the wellhead
- When taste, color or smell changes
- Before buying a property with a well
- If someone in the home is pregnant, an infant, or has a weakened immune system
Next steps if results come back high
A positive bacteria result often calls for well disinfection (shock chlorination) and retesting, plus a look at the wellhead seal. Mineral or nitrate issues may point toward treatment equipment or, in some cases, a different well. We can connect you with local well professionals who can help with sampling, disinfection and repairs.
